Embodiment 2

[0045] Embodiment 2: Method for setting the target blood oxygen value on the man-machine interface

[0046] When applying the oxygen therapy of the present invention, according to the patient's condition characteristics, operate the function keys of the man-machine interface to set the target blood oxygen value suitable for different patients, specifically:

[0047] (1) The target blood oxygen value of the anesthesia recovery patient is set to 96%, and the target blood oxygen control range control algorithm is automatically given according to "target blood oxygen value ± 2%", that is, the target blood oxygen control range of the patient is 94% ~98%;

[0048] (2) The target blood oxygen value of newborn patients with routine oxygen inhalation is set to 93%, and the target blood oxygen control range control algorithm is automatically given according to "target blood oxygen value ± 2%", that is, the patient's target blood oxygen control range Between 90% and 95%;

[0049] (3) T...

Abstract

The invention provides an oxygen output system based on cooperative control over a respiratory frequency and a target blood oxygen value. The system is mainly composed of a control module, a blood oxygen monitoring module, a respiratory frequency sensor, a flow control module, a flow cut-off valve, a human-computer interaction interface, a communication module and a control algorithm. The oxygen output system based on the cooperative control over the respiratory frequency and the target blood oxygen value has the advantages that the flow cut-off valve responds in real time according to respiratory frequency changes, so that oxygen output and breathing actions of a patient are kept synchronous, and the oxygen consumption is reduced by about 50% compared with the prior art; the blood oxygen monitoring module monitors whether or not the blood oxygen value of the patient is stably kept in a target blood oxygen control range in real time and dynamically adjusts the oxygen output flow to ensure the effectiveness and safety of the oxygen therapy.

Description

technical field [0001] The invention relates to an oxygen output system controlled cooperatively based on respiratory frequency and target blood oxygen value, which belongs to clinically used medical equipment. Background technique [0002] Medical oxygen output control equipment is a necessary medical device for medical institutions to perform oxygen therapy (referred to as "oxygen therapy"). Commonly used oxygen inhalers, ventilators, etc. The oxygen output control method of the existing oxygen therapy equipment is relatively mechanical and single. During the oxygen therapy, the medical staff set the output flow rate, oxygen inhalation time and other parameters to realize the oxygen output. Intelligent control cannot be realized according to individual differences of patients and changes in vital signs. [0003] In order to overcome the above defects, the inventor also proposed CN108744190A, CN104826204B and other technical solutions, although significant progress has bee...
